The transformer windings which are made of pancake a nd helical coils for the primary and the secondary respectively have uneven distri bution of magnetic-force, and produce the radial component of magnetic field wh ich should be considered in the calculation of leakage reactance. In this paper, a leakage reactance calculation is done in the transformer windings with the ab ove configurations and concentrically arranged "HV-LV-HV" on a core limb, and an equivalent transformation is proposed about the uneven distributed magnetic f orce, furthermore, the effect is analyzed on the leakage reactance by the coil p ancake number and the gap lengths among coil pancakes. The investigation shows t hat the fewer the number of the coil pancakes, the faster the leakage reactance changes with the gap lengths among coil pancake number. When coil pancake number reaches some value, the leakage reactance changes little with the gap lengths. Finally the method is verified by the result based on the calculation of leakage magnetic field distribution by finite element method (FEM).
